Magnetic field and dynamic pressure ULF fluctuations in coronal-mass-ejection-driven sheath regions [PDF]

Annales Geophysicae, 2013
Compressed sheath regions form ahead of interplanetary coronal mass ejections (ICMEs) that are sufficiently faster than the preceding solar wind. The turbulent sheath regions are important drivers of magnetospheric activity, but due to their complex ...

Demographic and Clinical Characteristics of Early‐Onset Colorectal Cancer in Sweden and Finland: A Multicentre Retrospective Cohort Study Over Three Decades

Journal of Surgical Oncology, EarlyView.
ABSTRACT Colorectal cancer is the third most common cancer worldwide, and the proportion of individuals diagnosed under the age of 50 years, referred to as early‐onset colorectal cancer (EOCRC), is increasing. The aim of this study was to evaluate how the demographic and clinical features of EOCR in northern Sweden and Finland have changed over time ...

Promoting Sustainable Prescribing-A Case Study Presenting Experiences From Two Swedish Drug and Therapeutics Committees. [PDF]

Pharmacol Res Perspect
ABSTRACT During the past two decades, it has become evident that pharmaceuticals is an emerging environmental problem. In this study, we present the experiences from two Swedish Drug & Therapeutics Committees (DTCs) on how they integrate environmental considerations into their formularies and continuous professional education activities.

Should Dermatologists Recommend Direct‐to‐Consumer App‐Based Remote Diagnostics? An Ethical Analysis

JEADV Clinical Practice, EarlyView.
ABSTRACT Background Dermatology patients still face barriers in accessing timely specialist care. As direct‐to‐consumer (DTC) apps for remote dermatological diagnostics proliferate, guidance is lacking. While promising efficiency and efficacy, their clinical—and ethical—legitimacy is not yet well established.

Recent Advances in Top‐Down Proteomics for Single‐Cell Research

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Individual cells have distinctive molecular characteristics, including biologically relevant proteoforms. Although single‐cell (SC) molecular omics offer unprecedented insights into cellular heterogeneity and function, the characterization of proteoforms in SCs remains an uncharted territory.

Time‐Conditioned Zero‐Shot Self‐Supervised Reconstruction for Accelerated 3D Ultra‐Low‐Field MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Ultra‐low‐field (ULF) MRI provides a cost‐effective, portable imaging option but has relatively low SNR and long acquisition times compared to standard clinical scans. This study presents a time‐conditioned zero‐shot self‐supervised learning image reconstruction framework (ULF‐ZS‐SSL) to accelerate 3D‐acquired single‐coil ULF MRI ...

Four Directions, One Solution: Enabling Rapid Diffusion Tensor MRI for Ultra‐Low Field Using Deep Learning

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose This study revisits the tetrahedral encoding strategy originally proposed to accelerate Diffusion Tensor Magnetic Resonance Imaging (DT‐MRI) by reducing the requisite number of diffusion‐weighted measurements to four. We examine its practical limitations and explore how artificial intelligence (AI) can extend its utility. Specifically,
